I'm a long time user of bs.player, and love my features about it. But I've been having a few issues recently.

I upgraded from 2.52 to 2.57 recently and have had problems with the subtiltes. On a widescreen monitor, when watching an sd video (ie. something with a 4:3 aspect ratio) the subtitles behave oddlty.

When watching a 4:3 movie in fullscreen mode on a widescreen monitor, there are obviously going to be black borders to the left and right sides (unless the resolution is stretched to widescreen, but that just makes everyone look fat). When using BS.Player 2.52, the subtiltes on a 4:3 movie file only show on top of the actual part of the screen where the video is playing. However, with 2.57 the subtitles on a 4:3 movie sometimes extend onto the black borders. And here is where the problems begin.

As way of an example, lets say the following line is being displayed onscreen:

The line is quite long, so "all right" and "loving you" are displayed in the black margins. However, when the next subtitle line displays, the all right / loving you words still linger. Over the course of the whole file, many words "ghost" in the black margins, and build up into an unreadable mess.

I tried other rendering options, and using "overlay mixer" seems to fix the problem, compared to the default "enhanced video renderer" option. However every time I play a file, Win7 gives me a warning that "[BS.Player] isn't compatible with certain visual element of Windows" and for the duration of the program windows switches to windows 7 basic. It seems overlay mode isn't compatible with aero themes.

It's not a huge problem though.

Regarding using overlay mixer vs. EVR, how do they compare? Is there a big difference in video quality eg when playing hd content?
